The Kingdom of Bahrain is a Middle Eastern archipelago in the Persian Gulf, tucked into a pocket of the sea flanked by Saudi Arabia and Qatar. It's an oasis of social liberalism – or at least Western-friendly moderation – among the Muslim countries of the region. It's popular with travelers for its authentic "Arabness" but without the strict application of Islamic law upon its non-Muslim minority. Case in point: alcohol is legal here. Although it has a heavily petroleum-based economy, its more relaxed culture has also made it a social and shopping mecca (so to speak), which has helped it develop a fairly cosmopolitan middle class not found in neighboring countries with just a rich elite and subsistence-level masses.
Here is a list of the UNESCO World Heritage Sites in Bahrain:
Qal'at al-Bahrain – Ancient Harbour and Capital of Dilmun in Northern Governorate, Bahrain
The site was the capital of the Dilmun, one of the most important ancient civilizations of the region. It contains the richest remains inventoried of this civilization, which was hitherto only known from written Sumerian references.
